In the above example I have used &val[i] to get the address of ith element of the array. We can also use a pointer variable instead of using the ampersand (&) to get the address. Example – Array and Pointer Example in C #include<stdio.h>intmain(){/*Pointer variable*/int*p;/*A...
printf("a value through pointer to pointer = %d", **q); } Output a=10 a value through pointer = 10 a value through pointer to pointer = 10

if you're not careful with memory management, especially in languages like c and c++, you risk memory leaks or double freeing, both of which can result in crashes or bugs. you have to be quite meticulous in managing both the array and the memory to which each pointer points. looking for...

Pointers are intimately associated with arrays. An array in C is evaluated as a constant pointer and therefore, we do not use the address operator with an array name. When an array is declared, the compiler allocates a base address (address of the 0th element) and a sufficient amount of...
C语言中的数组的一般声明形式如下: T arr_name[n]; /* T为类型,n为数组元素个数 */ 从内存布局角度来说,数组T arr_name[n]就是内存中连续的内存单元,每个内存单元的长度为sizeof(T),数组的起始内存单元地址为arr_name所在的内存地址, 同时也是数组第一个元素arr_name[0]的内存地址。
